So about 3 years ago I had this friend that at that time was a little more than a friend but it never worked out for us... After me and him went our separate ways I met my now fiance but this other guy just keeps popping up in our relationship. My fiance is constantly accusing me of cheating with him and I'm starting to get real frustrated with the whole situation. How do I continue with my relationship if he continues to accuse me of doing things that I'm not doing
